2. Safety Information

WARNING: Read and understand all safety precautions and instructions in the complete operator manual before operating this generator. Failure to follow these instructions may result in serious injury or death.

General Safety Guidelines:

• Carbon Monoxide Hazard: Generators produce carbon monoxide, an odorless, colorless gas that can kill you. Operate the generator outdoors only, far away from windows, doors, and vents.
• Electrical Shock Hazard: Never operate the generator in wet conditions. Ensure proper grounding to prevent electrical shock.
• Fire Hazard: Fuel is highly flammable. Always refuel in a well-ventilated area with the engine off and cool. Do not overfill the fuel tank.
• Hot Surfaces: The generator's engine and muffler become very hot during operation and remain hot for a period after shutdown. Avoid contact to prevent burns.
• Proper Grounding: Always ensure the generator is properly grounded before operation. Refer to your local electrical codes and the operator manual for specific grounding instructions.
